QUICK UNFOLD is a newly added function, which allows the user to use MSTEP and estimate a blank size within a short time. The interface is illustrated in Figure 7.1.1.
The user may click the Import button to import the model file (IGS and NASTRAN formats). Please refer to Section 3.6 for a detailed description of importing geometry file. If a model in IGS format is read in, the program will automatically estimate a reference value for element size according to the model size and allow the user to change this value. If a model in NASTRAN format is read in, the Element Size is disabled.
After reading in the model file and setting Element Size and Blank Thickness, click the OK button. The program will automatically tip the model mesh and use MSTEP to estimate the blank outline size for the model after tipping. The estimated blank outline will be automatically saved in the new part of OUTLINE.
